WINDING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 630,343, dated August8, 1899. Application filed December 2, 1897. Serial No. 660,484. (Nomodel.)

To all whom it may concern:

Be it known that I, SAMUEL M. GREEN, a citizen of the United States,residing at Holyoke, in the county of Hampden and State ofMassachusetts,have invented certain new and useful Improvements inWinding-ltfaehines; and I do hereby declare the following to bee. full,clear, and exact description of the invention, such as will enableothers skilled in the to make and use the art to which it appertainssame.

My invention relates to thread-windin g machines of the class in whichthe thread is laid upon the bobbin bya reciprocating or vibrat: ingthread-guide which traverses from end to end of the bobbin, inconnection with a presser-roll which bears against the bobbin andprevents any disarrangement of the layers of thread. a

The object of the invention is to provide such machines with a form ofthread-guide which will secure a more accurate delivery of the thread tothe bobbin and enable'the machine to be operated at a higher speed thanhas heretofore been practicable.

To this end the invention consists in the combination, with awinding-machine ofthe class mentioned, of a thread-guide constructed andoperating as hereinafter fully described, and particularly pointed outin the claims.

Referring to the drawings, in which like numerals designate like partsin the several views, Figure 1 is a plan view of a windingmachineembodying the invention. Fig. 2 is a side view thereof with thestop-motion mechanism omitted. Fig. 3 is an end view of the same,looking toward the left in Figs. 1 and 2, with the threadguide andpresser-roll in their working position.

The frame 1 of the machine is provided with suitable bearings forsupporting the main shaft 2, which carries fast and loose pulleys 3, bywhich motion is communicated to said shaft through a belt 4:. Said shaftalso carries a spur-gear 5, whichmeshes with a large gear 6, carried bya shaft 7, which shaft is supported in bearings on standards 8 of theframe and carries between said standards the cam-wheel 9, having theperipheral groove 10, which forms an ellipse. At the upper end of astandard 12 on the frame is a long bearing 13, which supports thespindlepro ecting roll the frame 20 shaft 14:, said shaft carrying atone end the winding-spindle 15, upon which the bobbin 16 is wound, andat its opposite end the pulley 17, which pulley is connected with anoppositely-inclined pulley 18 on the main shaft 2 by abelt 19. Thepulleys 17 and 18 are slightly tapered, but not sufficient to indicatein the drawings on the scale therein shown, and the faces of the pulleysare wider than thebelt 19. By shifting said belt 19 upon said cone-facedpulleys any desired degree of difierence in speed between thespindle-shaft 14: and cam-shaft 7 can be secured, as is common in thisclass of machines. A frame 20, loosely hung on the cam-shaft 7, carriesat its upper end'the revoluble presserroll 21 and is provided with theforwardly- V arm 22, upon which is mounted the weight 23, the action ofwhich is to tilt the frame 20 forwardly in such manner as to hold theroll 21 against the bobbin 16 with a considerable degree of pressure,while permitting it to yield to the increasing diameter of the bobbin.At the rear of said presseris provided with a groove extending parallelwith the axes of said roll and the winding-spindle, into which grooveprojects a rib 24 on the front side of a slideplate 25, a back piece 26,secured to the said frame 20 at the rear of said slide-plate, serving tomaintain the latter in such position while permittin it to reciprocatefreely upon the frame. Said slide-plate carries the depending stud andantifriction-roll 27, which enters the groove 10 of cam-wheel 9, wherebysaid slide-plate is given one complete reciprocation with eachrevolution of said wheel. To the upper end of said slide-plate issecured the thread-guide 28, consisting of a narrow strip, preferably ofsheet-steel, which is curved forwardly and downwardly, as shown in Fig.3, to cause its front end to enter between the presser-roll and thebobbin, said end terminating immediately adjacent to the point ofcontact between said roll and bobbin. On its upper side the thread-guideis provided with the guiding pins or studs 29, between which the threadis guided, and at its front end it is provided with the threadguidingnotch 30 to cause the thread, to follow it in its traversing movement.By so constructing said thread-guide as to cause it to deliver thethread tothe bobbin at the point of contact of the latter with thepresser-roll every layer of thread on the bobbin is deposited andforcibly held in close contact with the preceding layer in such manneras to form a more compact bobbin than can be wound with the deliveringend of the thread-guide in any other position, and this is especiallytrue of a bobbin of the character shown, in which each layer of threadextends from end to end of the same. Such perfect. control of the threadduring the entire operation of winding a bobbin enables the bobbin to bewound at a considerably higher speed than has been practicable with theforms of th readguide heretofore employed.

The machine herein shown is provided with a stop-motion mechanismcomprising a sliding bar 31, carrying belt-shifting pins 32, engagingthe belt 4, and a brake-shoe 33, adapted to engage a web on the innerface of the conepulley 18 and having a notch in its upper edge intowhich drops an arm 34 on a lever 35, pivoted at 36 on the machine-frameto normally'retain said bar in its retracted po sition, a spring 37serving to press said bar in a direction to shift the belt 4 to theloose pulley and to force the brake-shoe 33 against pulley 18. otherforwardly-projecting arm 38, carrying the weight 39, and with arearwardly-extending arm 40, the end of which underlies the lower end ofa drop-wire 41, which is guided for vertical movement upon a standard 42and carries at its upper end a loop 43, through which the thread passesand by which it is normally retained in its elevated position. Thethread 44 is led from the supply spool or reel (not shown) through saidloop 43 'on the drop-wire and from thence between the pins 29 andthrough the notch 30 on the threadguide to the bobbin, and when thethread breaks the drop-wire falls-and rocks the lever 35, therebyreleasing the bar 31, which causes the instant stoppage of the machine,as described. Such stop-motionmechanism and the particular means forsecuring the reciprocating movement of the thread -gnide may be variedas may be desired, the means herein shown for securing said functionsbeing shown merely as illustrations of the various forms of such meanswhich can be utilized.

It will be obvious that so far as mypresent invention is concerned it isimmaterial whether the presser-roll and thread-guide be movable towardand away from the bobbin, as herein shown, or whether the said roll andguide be mounted in stationary bearings and the bobbin-spindle besupported in movable bearings and pressed against the presser-roll tosecure the result herein described; but I prefer to make thepresser-roll the movable member, as shown. a

It will be noted that the thread-guide devised by me does not come incontact with the surface of the bobbin during any portion The lever 35is provided with an-' of the winding operation of the latter, therebyobviating any fraying of the thread and enabling the bobbin to be woundat a much higher rate of speed than is possible when a thread-guide isused which bears upon the surface of the bobbin.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a winding-machine, the combination with a rotating spindle, meansfor driving the same at a varyingspeed, a yielding frame, a,presser-roll carried by said frame in contact with the bobbin on saidwinding-spindle, ways'on said frame parallel with the axis of saidpresser-roll, a thread-guide having a reciprocating motion along saidways and means for imparting a determinate reciprocating motion to saidthread-guide, substantially as described. i

2. In a winding-machine, the combination with a shaft carrying awinding-spindle, a presser-roll mounted upon a pivoted support wherebyit is movable toward and away from the face of a bobbin on said spindle,means for exerting an elastic pressure uponsa'id support to press saidroll against the bobbin during the winding of the latter, a threadguidemounted upon said pivoted support and adapted for longitudinal movementthereon in a plane parallel with the axis. of said roll,

a shaft carrying a face-cam which engages said thread-guide forimpartinga reciprocating movement thereto, a main driving-shaft, andmeans for transmitting movement from said main shaft to said spindle andcam shafts.

3. In a winding-machine,the combination of a rotating winding-spindle,ayieldingframe, a presser-rollcarried by said frame, a threadguidecarried by said yielding frame, said guide being curved over-saidpresser-roll and having guide-pins over said roll and an eye in its end,whereby the thread is delivered in a line tangential to the presser-rolland in juxtaposition to its point of contact with the bobbin,substantially as described.

4. In a winding-machine,the combination of a winding-spindle 15, meansfor rotating said spindle at a varying speed, a pivoted frame 20, apresser-roll journaled in said frame, a slide-plate sliding in ways onsaid pivoted frame, a cam by which said plate is reciprocated and curvedthread-guide 28 carried by said sliding plate and extending over. said'presser-roll, said guide having guiding-pins 29 and a notch, or eye,.3Oin its free end, said free end being included in the angle. between thepresser-roll and the bobbin, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
